Abstract
The reaction of aryl iodides with an activated methine compound, diethyl acetamidomalonate, can efficiently proceed in the presence of CuI and NaH in DMSO to give diethyl acetamido(aryl)malonates, which may be useful precursors for α-arylglycines, in good yields. Although the reaction with another methine substrate, ethyl 2-cyanopropionate, also affords the expected coupling products, no substitution products are obtained in the case of diethyl methylmalonate, arenes together with an oxidative coupling compound of the ester being formed.
